TPA3112D1QPWPRQ1 Frequently Asked Questions (FAQs)

  • According to TI's application note, a 10uF ceramic capacitor and a 100nF ceramic capacitor in parallel, placed close to the power pins, are recommended for power supply decoupling.
  • TI recommends a 4-layer PCB with a solid ground plane, and to keep the audio signal traces away from the power supply traces. Additionally, use a star-grounding configuration and avoid routing audio signals under the IC.
  • The maximum power dissipation of the TPA3112D1 is 3.5W, and it's recommended to keep the junction temperature below 150°C to ensure reliable operation.
  • Yes, the TPA3112D1 can be used in a bridged configuration, but it requires an external amplifier to drive the other half of the bridge. TI provides an application note with a reference design for a bridged amplifier.
  • TI recommends using a voltage supervisor or a reset IC to monitor the power supply voltage and reset the amplifier if it falls outside the recommended operating range.
